GARD-ROLL-STRIPPING APPARATUS.

Specification of Letters Patent.

Patented May 16, 1916.

Application filed June 11, 1912. ScrialNo. 702,953.

To all whom it may concern:

Be it known that we, .ELWIN H. RODNEY and J OHN T. WILD, both citizens of the United States, and residents of Whitinsville, in the county of Worcester and State of Massachusetts, have invented the following described Card-Roll-Stripping Apparatus.

The invention is an improved means for cleaning or stripping card rolls, the object being to provide an apparatus for this purpose of such efliciency as to be capable of operation by hand power alone and adapted to be readily moved about fro-m place to place where needed, and which will collect and contain its own dirt and remove the same from the card rolls without scattering lint into the surrounding air, and will otherwise serve as a convenient and practicable means for cleaning the clothing of the card rolls.

To this end the invention consists in the essentialcombin at-ion of aznotary card-clothed stripping cylinder and a support which holds the roll to be stripped in free rolling contact therewith as distinguished from prior devices of like purpose which operate by difierence in motion, that is to say, devices in which the stripping cylinder is rotated at a different surface speed from that of the roll to be stripped, and with which it has contact for the purpose of brushing or combing out the dirt and lint.

According to this invention the roll to be stripped and the cylinder which is to strip it are both rotated at equal surface speeds in contact with each other and with the card teeth on one intermeshing with those on the other. The simple rolling motion removes and loosens the dirt and lint and transfers the same in a flocculent condition to the strippingcylinder from which some of it:

may fall by gravity, while the remainder can be removed with very little effort, as, for instance, by revolving the cyllnder agalnst a brush or a comb, or slmllar cleaning devlce.

The stripping cylinder is preferably pro vided with long card teeth which will thereby accommodate a large amount of stripping before needing to be cleaned itself and which at the same time facilitates such cleaning when undertaken, and such cylinder is preferably rotated so that its card teeth approach the roll to be stripped point first,

with ample penetration into the clothing thereof.

To accomplish the result above described a varlety of different forms of embodiment of the principle of this invention may be employed, a single and preferred form being lllustrated in the accompanying two sheets ofdrawings, wherein Figure 1 is a perspective view of the new apparatus in operation by hand and engaged 1n simultaneously stripping two card rolls. F g. 2 is an end view of such apparatuswithout the rolls, showing the shaft of the strip ping roll in section. Fig. 3 is a cross-section of the apparatus. Fig. 4 is a longitudinal vertical section thereof, on line IV-IV of Fig. 2. Fig. 5 is a detail of one ofthe adustable journal seats for the roll to be stripped. Fig. 6'is a detail in plan showing the folding brackets on the exterior of the receptacle, and Fig. 7 is a broken perspective view of the cleaning device inside of the receptacle.

The apparatus comprises a suitable framework 1, paneled on its ends and sides to form a receptacle to receive and contain the strippings. Such receptacle is desirably mounted on truck wheels, as illustrated, and its vertical dimension is adequate to permit the stripping cylinder therein to be conveniently rotated by the operative in standing posture. One or both sides of the receptacle is provided with a hinged door, as shown at 2, through which the strippings indicated at 3, can be removed.

The rotary stripping cylinder 5 is carried in journal seats 4, formed in or provided on the end walls of the receptacle, near the vertical center line thereof, and at such height as will bring the upper surface of the said cylinder slightly below the upper margin of the receptacle. This cylinder is clad with card clothing of a'co mmon type and such as indicated in the drawings, wherein it will be observed that the card teeth are somestripped. Inasmuch as the operation of rotating this stripping cylinder is accomplished with the application of very little force, the journal seats 1 may be open bearings or notches in which the cylinder is maintained by its own weight, as well as by the pressure of the card rolls, and from which it may be readily removed if necessar fit one side of the stripping cylinder the receptacle is provided with a pair of bearings or journal seats 8, in which the roll to be stripped, marked 12, is adapted to be placed, there being one such ournal seat at each end of the receptacle, as shown 1n Fig. 4. Each of these journal seats is mounted. for vertical adjustment upon a slidway 9, which is permanently fastened to the end wall of the receptacle, and such adjustment is imparted to the journal seats by the appropriate rotation of the screw 10 and set by the clamp-bolt 11. The roll to be stripped rests by its axle-ends in these hearings, the part designated 13 in Fig. 5 being a sleeve which forms the bearing for the roll when performing its normal function in the carding machine; as shown in Fig. 5 this sleeve may remain on the axle and rest on one of the bearings 8. The said bearings are adjusted to such vertical positions as will permit the roll 12 to rest gravitationally upon the card clothing of the stripping cylinder, as well as upon the journal seats, substantially in the relation indicated in Fig. 3, that is to say, the said roll is supported partly by the stripping roll and partly by the adjustable journal seats, which. are set accordingly. Thereby the card roll is adapted to be rotated by the rotation of the cylinder 5, and at the same surface speed. The apparatus taken for illustration of the invention also comprises another like pair of journal seats 14:, similarly mounted on the receptacle on the opposite side of the stripping cylinder but at a less distance from the vertical plane thereof. These journal seats are for similarly supporting a card roll of different diameter, as shown at 15. Both journal seats, as a matter of convenience, are open bearings or U-shaped sockets and the axles of the card-rolls such as 12 and 15, are unconfined therein save by gravity. When one or both rolls have been placed in their appropriately adjusted journal seats, in which condition they are parallel to the stripping cylinder, rotation of the latter in the direction of the arrow indicated in Fig. 3, will cause such roll or rolls to revolve in the direction of the arrows applied to them and will thereby immediately transfer the dirt on the latter to the card clothing of the stripping cylinder, one revolution of the latter being ordinarily sufficient to effect the complete transfer.

After a. number of such rolls have been stripped in this manner and their dirt and lint transferred to the stripping cylinder, the latter is cleansed of the strippings by rotation in the opposite direction and while in engagement with the cleaning device shown at 16, which consists merely of a card clothed plate resembling an ordinary hand-stripper, mounted on arms 17, secured to a longitudinal rock shaft 18, which latter is appropriately journaled in the walls of the receptacle and provided with an exterior handlever 19, by which it may be rocked into and out of a position substantially tangential to the surface ofthe stripping cylinder, as indicated by the dotted lines in Fig. 3. A few rotations of the cylinder, done by hand, will remove the entire accumulation of strippings, whereupon the cylinder is ready for further use.

Pairs of folding brackets 20 are hinged to the exterior of the receptacle by bolts or pins 21 (Fig. 6) and are each provided with a leaf spring 22, for holding them either in projecting relation, as shown in full lines, or in positions folded back against the side walls of the receptacle, as indicated by the dotted lines. The rolls to be stripped can be supported and transported prior and subsequent to their introduction to the journal seats 8 or 14, on these brackets, of which any desired number can obviously be provided.

It will be observed thatthe roll to be stripped is provided with no means for rotating it beside the engagement of its card teeth with the card teeth of the stripping cylinder, and that such rotation takes place freely and with no greater friction than is necessarily present between the axle of such roll and the journal seat thereof. The two card-clothed cylinders thus rotate equally or at equal surface speeds, which provides the advantage above referred to, that the apparatus can be operated by hand power and most conveniently so. The same consideration permits the apparatus to be made of comparatively light construction and hence easily transported about the card room, and it also permits more than one card roll to be cleansed at the same time.

From the foregoing it will further be ob served that our invention involves also the method of stripping above described which consists in transferring the strippings through free rolling contact of one cardclothed cylinder on a second card-clothed cylinder from which such strippings are then removed and such method may be employed in other obvious relations than that above specifically described.
